Smart completion of variable/field based on method return type about meghanada-server HOT 4 CLOSED

No, it must do all of the server. Server analyzed the source, it has type information and expression information and you need to implement it using it.
Contributions are extremely welcome !
Thanks.

Got the thoughts, that's reasonable design, I will try to implement it.

Then we can discuss on how to handle basic completion and smart completion and make them work at the same time.

Thanks.

Basically in order to make it easier for end user, I have combine the so called "smart completion" and normal completion together through implement a custom comparator for CandidateUnit, and offers higher rank for those with exactly same return type with the variable/field to be assigned.

The current implementation logic is:

For the follow code fragments

String a = "";
int i = a. //<-- Cursor position 

String a = "";
int i = 0;
i = a.//<-- Cursor position

public class A {
  private int intMember;
  private void aMethod() {
    String a = "";
    intMember = a. //<-- Cursor position 
  }
}

then all methods of String class with return type of int will be list before other methods.

Current support:

• class member assignment
• local variable assignment

Note:

• For code fragment 2 and 3, the buffer needs to be saved first for the meghanada-server to generate correct output, otherwise the return list will be same as current.
• For code fragment 1, I will sent the type information(int) directly from Emacs to server side for it to do match, so there's no need to save the buffer.

Thanks :)

Already added generic support for the smart completion of assignment.
